Description

Technical Field

[0001] This invention relates to the field of cheese production technology, and in particular to a discharge sealing door assembly and a cooking and stretching machine containing the assembly. Background Technology

[0002] In the cheese production and processing industry, the cooking and stretching machine is the core equipment for achieving high-temperature cooking, stretching, and shaping of cheese. The sealing door assembly at its discharge end directly affects the equipment's sealing performance, production continuity, and product hygiene quality. After cooking and stretching, cheese is in a high-temperature, high-viscosity state. When the discharge sealing door is opened, a large amount of cheese material inevitably adheres to the inside of the door panel facing the discharge port. If this is not cleaned in time, it will have many adverse effects on subsequent production.

[0003] Currently, the industry primarily relies on manual scraping to remove cheese adhering to the inside of the door panel. The specific procedure involves: after the discharge sealing door is fully open and material delivery is complete, workers use a scraper to reach into the discharge area and manually scrape off the cheese adhering to the inside of the door panel. The scraped cheese material needs to be collected and processed separately before the door is closed and the next production step begins, impacting production efficiency. Secondly, during cheese production, the discharge sealing door and surrounding area remain at high temperatures. Manual scraping in this high-temperature environment is physically demanding and increases the risk of burns. Furthermore, workers frequently need to approach the discharge port; if the equipment malfunctions or the interlock fails, it could cause mechanical injury, posing a safety risk. Summary of the Invention

[0004] Therefore, it is necessary to address the above-mentioned technical problems by providing a discharge sealing door assembly capable of scraping off cheese adhering to the door panel during discharge, and a cooking and stretching machine containing the assembly.

[0005] The present invention provides a discharge sealing door assembly, comprising a housing and a storage slot formed inside the housing, and further comprising: Two rotating shafts are rotatably installed inside the storage slot. The stirring plate is fixedly sleeved on the outside of the rotating shaft and is designed in a spiral shape.

An arc-shaped groove is provided on the rotating rod, and a limit rod is fixedly installed on the inner wall of the cylinder. One end of the limit rod is slidably fitted with the arc-shaped groove.

[0010] In one embodiment, a limiting block is fixedly provided on the discharge port of the housing, and the bottom of the limiting block is movably abutting against the top of the scraper.

[0011] In one embodiment, a horizontal plate is fixedly provided on one side of the movable frame, and abutment plates are axially symmetrically fixed on both sides of the movable plate away from the fixed cylinder, and the horizontal plate and the abutment plates are movably abutted together.

[0012] In one embodiment, a horizontal groove is provided on the top of the movable plate, and a movable plate is movably disposed in the horizontal groove. The bottom of the movable plate is fixedly connected to the top of the door panel.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0026] The following is combined with Figures 1-12 This invention describes a discharge sealing door assembly and a cooking and stretching machine containing the assembly.

[0027] like Figures 1-4 As shown, in one embodiment, a discharge sealing door assembly includes a housing 1 and a storage slot 101 formed inside the housing 1, and further includes: Rotary shaft 2 is rotatably installed inside storage slot 101, and the quantity is set to two; The stirring plate 3 is fixedly sleeved on the outside of the rotating shaft 2 and is designed in a spiral shape. The discharge port 102 is located on one side of the shell 1; The fixing rod 4 is axially and symmetrically fixed at both ends of the housing 1 on the side of the discharge port 102; The movable plate 5 is slidably connected to the fixed rod 4 at both ends; Door panel 6 is movably installed inside movable panel 5, and has a groove 61 on it; The scraper 7 is movable inside the door panel 6; The scraper assembly 8 is located on one side of the door panel 6 and is used to drive the scraper 7 to move up and down.

[0028] Specifically, the equipment is started, and the cooking chamber and stretching chamber are preheated with steam / heat transfer oil. The temperature inside the storage trough 101 of the shell 1 is controlled at 85~95℃. Cheese curd is added. During the cooking process, the rotating shaft 2 inside the storage trough 101 drives the stirring plate 3 to rotate. The stirring plate 3 is designed in a spiral shape to ensure that the curd is heated evenly and kneaded into a whole. At this time, the part of the door plate 6 without the slot 61 abuts against the discharge port 102 to achieve a seal on the discharge port 102 and ensure the airtightness of the shell 1 during cheese processing. After the cheese processing is completed, the movable plate 5 is moved upward along the fixed rod 4. The movement of the movable plate 5 will drive the door plate 6 and the scraper 7 to move upward synchronously. During the upward movement, the scraper 7 moves downward relative to the door plate 6 through the hanging component, which can scrape off the cheese adhering to the end of the door plate 6 near the discharge port 102. The scraped cheese falls off the door plate 6 and falls to the bottom, eliminating the need for manual scraping, improving work efficiency, and avoiding the harm to the human body caused by high temperature.

[0029] See Figure 4 As shown, in this embodiment, the scraping assembly 8 includes a movable frame 81, which moves laterally relative to the slot 61. Multiple fixed cylinders 82 are fixedly installed in a horizontal linear array on the top of the movable frame 81. A movable rod 83 is movably arranged inside the fixed cylinder 82. The end of the movable rod 83 away from the fixed cylinder 82 is fixedly connected to the top of the scraper 7, and the end of the movable rod 83 away from the scraper 7 is elastically connected to the inner wall of the fixed cylinder 82.

[0030] Specifically, when the outlet 102 is closed, the movable plate 5 is not in contact with the housing 1 at one end, but there is a gap between them. The door panel 6 is in contact with the housing 1 at one side, which ensures the sealing of the outlet 102. The scraper 7 is in contact with the housing 1 at one end. When the cheese is made, the movable plate 5 moves the door panel 6, the movable frame 81, the scraper 7, and other components upward together. It will first move laterally, and the movable plate 5 will move away from the outlet 102. The door panel 6 will move laterally at the same time, exposing the side with the cheese. As the door panel 6 moves away, the movable frame 81 moves towards the outlet 102. When one side moves, the fixed cylinder 82, the movable rod 83, and the scraper 7 move laterally towards the housing 1 in sync. The scraper 7 moves to the outside of the door panel 6. Then, the scraper 7 is pressed down and moves downward along one side of the door panel 6 to scrape off the adhered cheese. During the downward movement of the scraper 7, the movable rod 83 is pulled downward to ensure the stability of the scraper 7 during its movement. Since the movable rod 83 is elastically connected to the fixed cylinder 82, when the downward force applied to the scraper 7 is removed, the movable rod 83 will move upward to the initial position under the action of the pulling force.

[0031] See Figures 4-7As shown, in this embodiment, the scraper 7 has an internal movable groove 71, and a base plate 9 is movably disposed in the movable groove 71. The top of the base plate 9 is fixedly connected to the upper inner wall of the movable groove 71 by a plurality of return springs 10.

[0032] Specifically, as the scraper 7 moves downward along the door panel 6, it will gradually scrape off the adhered cheese. However, some cheese will also adhere to the bottom. The bottom plate 9 moves up and down along the movable groove 71. During the movement of the bottom plate 9, the cheese will be accelerated to detach from the bottom plate 9. During the movement of the bottom plate 9, the return spring 10 will deform. With the help of the characteristics of the spring, the bottom plate 9 will vibrate to a certain extent, so as to avoid too much cheese adhering to the bottom plate 9.

[0033] See Figures 6-9 As shown, in this embodiment, a positioning disk 11 is fixedly provided on the top of the base plate 9. Multiple circular holes 111 are arranged in a ring array on the positioning disk 11. A rotating rod 12 is movably provided through the top of the movable groove 71. One end of the rotating rod 12 is located above the positioning disk 11, and a disc 13 is fixedly provided at the end. Multiple spheres 14 are arranged in a ring array on the disc 13. The spheres 14 movably abut against the circular holes 111.

[0034] Specifically, as the scraper 7 moves downward along the door panel 6, the rotating rod 12 is rotated. The rotation of the rotating rod 12 will drive the disc 13 to rotate, and the rotation of the disc 13 will drive the ball 14 to rotate. When the ball 14 rotates to the point where it no longer abuts against the round hole 111, it will push the positioning plate 11 to move downward, causing the bottom plate 9 to move downward and stretching the return spring 10. When the ball 14 rotates to align with the round hole 111, the return spring 10 will pull the bottom plate 9 and the positioning plate 11 to move upward. Repeating this process will cause the bottom plate 9 to vibrate, accelerating the separation of the cheese.

[0035] See Figure 5 and Figure 8 As shown, in this embodiment, a cylinder 15 is fixedly installed on the top of the movable frame 81, and the end of the rotating rod 12 away from the disc 13 is slidably connected to the cylinder 15. An arc groove 121 is provided on the rotating rod 12, and a limiting rod 16 is fixedly installed on the inner wall of the cylinder 15. One end of the limiting rod 16 is slidably attached to the arc groove 121.

[0036] Specifically, when the scraper 7 moves downward relative to the movable frame 81, it will pull the rotating rod 12 to move downward relative to the cylinder 15. Since the rotating rod 12 has an arc groove 121 on its outer side and a limit rod 16 is slidably attached to the arc groove 121, the rotating rod 12 will also rotate synchronously during its downward movement. The rotation of the rotating rod 12 can ultimately achieve the reciprocating shaking of the base plate 9.

[0037] See Figure 3 and Figure 4As shown, in this embodiment, a limiting block 17 is fixedly installed on the discharge port 102 of the housing 1, and the bottom of the limiting block 17 is in movable contact with the top of the scraper 7.

[0038] Specifically, the movable plate 5 drives the door panel 6, movable frame 81 and other components to move upward, and then moves horizontally to the side away from the discharge port 102. When it moves vertically upward again, the top of the scraper 7 will abut against the bottom of the limiting block 17. When the scraper 7 continues to move upward synchronously with the movable plate 5, the scraper 7 will move downward under the action of the limiting block 17 to scrape and clean the cheese stuck to one side of the door panel 6. This allows the cheese to be scraped off simultaneously during the opening of the door panel 6.

[0039] See Figure 3 and Figure 10 As shown, in this embodiment, a horizontal plate 18 is fixedly installed on one side of the movable frame 81, and abutment plates 19 are axially symmetrically fixed on both sides of the movable plate 5 away from the fixed cylinder 82, and the horizontal plate 18 and the abutment plates 19 are in movable contact.

[0040] Specifically, when the movable plate 5 drives the door panel 6, movable frame 81 and other components to rise synchronously, the movable frame 81 will drive the horizontal plate 18 to move laterally. Since one side of the horizontal plate 18 abuts against the abutting plate 19, the horizontal plate 18 will move laterally in the opposite direction due to the limiting effect of the abutting plate 19 during its movement. This will drive the movable frame 81, scraper 7 and other components to move laterally in the opposite direction, so that the scraper 7 moves to the outside of the door panel 6, making it easier to move downwards to clean the stuck cheese.

[0041] See Figure 10 and Figure 11 As shown, in this embodiment, a horizontal groove 51 is provided on the top of the movable plate 5, and a movable plate 20 is movably arranged in the horizontal groove 51. The bottom of the movable plate 20 is fixedly connected to the top of the door panel 6.

[0042] Specifically, the moving plate 20 moves laterally along the transverse groove 51, which in turn causes the door panel 6 to move laterally. The door panel 6 moves away from the housing 1, so that the end with the cheese adhering to it does not come into contact with the housing 1, making it easier for the scraper 7 to scrape and clean it laterally.

[0043] See Figures 10-12 As shown, in this embodiment, a vertical groove 52 is provided on one side of the movable plate 5. The vertical groove 52 is connected to the horizontal groove 51. A positioning rod 21 is movably arranged in the vertical groove 52. The positioning rod 21 is fixedly connected to the movable plate 20 through a connecting plate 22.

[0044] Specifically, the horizontal movement of the positioning rod 21 along the vertical groove 52 will cause the connecting plate 22 to move synchronously, thereby causing the moving plate 20 to move, thus realizing the horizontal movement of the door panel 6 and the scraper 7, which facilitates the scraping of cheese adhering to one side of the door panel 6.

[0045] See Figures 10-12 As shown, in this embodiment, a limiting plate 23 is movably arranged in the vertical groove 52. The top of the limiting plate 23 is fixedly connected to one side of the housing 1. An inclined groove 231 is opened on one side of the limiting plate 23, and one end of the positioning rod 21 is slidably embedded in the inclined groove 231.

[0046] Specifically, when the movable plate 5 moves upward, the limiting plate 23 moves downward relative to the vertical groove 52, and the positioning rod 21, the connecting plate 22 and the door panel 6 move upward synchronously. During the upward movement, the positioning rod 21 moves from the lower part to the higher part along the inclined groove 231. The positioning rod 21 moves laterally relative to the vertical groove 52, which drives the connecting plate 22 to move laterally, so that the movable plate 20 moves along the horizontal groove 51 to the end away from the discharge port 102, so that the door panel 6 no longer abuts against the shell 1, making it convenient to scrape off the stuck cheese.

[0047] See Figures 1-3 As shown, in this embodiment, the movable plate 5 is driven by the piston rod 24.

[0048] Specifically, the up-and-down movement of the movable plate 5 is driven by the piston rod 24.

[0049] In this embodiment, a cooking and stretching machine includes the above-mentioned discharge sealing door assembly.

[0050] Specifically, in addition to the sealed door, the steaming and stretching machine also includes a temperature control system to control the temperature inside the shell 1. Furthermore, the rotation speed of the rotating shaft 2 also needs to be adjusted according to actual needs.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
